A 52 years old male patient, with a history of Gastrointestinal Stromal Tumor (GIST) in the small intestines with metastasis to the liver and peritoneum, with pathology showing mutation type Exon11. The patient underwent 18F-FDG PET/CT scan that showed lesions with moderate FDG uptake. The patient was given Sunitinib 50 mg p.os and a 18F-FDG PET/CT scan performed two weeks later showed marked reduced FDG uptake in all lesions. However, due to side effects, Sunitinib was first discontinued and then restarted after three weeks with 25 mg (half dose). A follow-up 18F-FDG PET/ CT scan three months later showed stable disease but high FDG uptake in multiple cervical, axillary and mediastinal lymph nodes.
